Hunting on Kunderer

William Barton's first novel, originally published in 1973, in which, as the Ace cover copy asserted, "On the planet primeval, the hunters can become the hunted." In the story, an oddball assortment of vacationers go on a dinosaur hunting safari, unknowingly pursued by an obese lunatic starship captain and his shaggy, purple hunting guide. This was the last original Ace Double book.
